Patented July 4, 1 939 LADLE AND MEANS FOR surroa'rmc 'nm SAME Einar 0. Holmberg, Wauwatosa, Wis., assignor to A. 0. Smith Corporation, Milwaukee, Wis., a corporation of New York Application August 7, 1937, Serial No. 157,846

3 Claims.

The present invention relates to an improvement in means for supporting ladies and other containers. In an application of Howard H. Needham, Henry A. Schmitz, Jr., and Frederick 5 K. Zerbe, Serial No. 154,970, filed July 22, 1937, for Supporting means for ladles, assigned to the A. O. Smith Corporation of Milwaukee, Wisconsin, the assignee of the present application, there is disclosed a support in which a ladle hangs and on which trunnions are mounted independent of the ladle. member having an upper ring upon which the ladle rests and which carries the entire weight of the ladle and its contents.

This invention provides an improvement in the utilization of the support disclosed in the aforementioned application. By this improvement it is possible to utilize a portion of the ladle shell to more efllciently transfer the load from the support to the ladle.

The object of the invention is to provide a the ladle 2 a short distance from the top of the' ladle. The ring Irests on the support. 3 which encloses the ladle but is not'connected to it. A pair of trunnions I, which have no connection with the ladle, are mounted on opposite sides of the support 3. The method of mounting the -trunnions 4 is set forth in the Needham et al application and will not here be repeated.

As disclosed in said application, the support 3 has a ring 5 upon which ring I of the ladle rests. To safely carry the ladle this ring 5 must be of relatively heavy construction and one of the principal elements in the cost is in rolling the ring for a large sized ladle.

In the present invention fillets or cleats 6 are welded to fie insideof the ring 5 above the trunnion mountings. The fillets do not extend the full circumference of the shell, and expansion of the ladle, caused by the heat of its molten contents, may occur in a lateral direction without affecting the support in a serious manner.

The fillets are tapered to complement the taper of the ladle shell and form a seat upon Ihlchtheshellproper mayrest. Inthismanner The support embodies an enclosingpart of the stress caused by the vertical force of the ladles weight on ring 5 is transferred to the shell by an oblique force through the fillets. The stress on ring I is also relieved in the area where the upward pull on the trunnions exerts the greatest force.

ladies.

The invention having been described, what is claimed is:

1. In combination with a ladle having an inw'ardly extending taper toward the bottom and an outwardly extending flange near the top thereof, supporting means enclosing said ladle and upon which said flange rests, said means including fillets, tapered to complement the taper of the ladle shell, disposed between said supporting means and said shell and extending circumu ferentially of the shell a short distance on either side of each trunnion, for transferring part of the weight of the ladle to the supporting means directly through the ladle shell, the remainder of said supporting means being spaced from the ladle shell and unsecured thereto. a

2. In combination with a ladle having an outwardly extending flange near the top thereof, a support enclosing said ladle and upon which trunnions are mounted independent of the ladle, comprising an upper ring upon which the flange of the ladle rests, said ring having an inwardly extending portion above the trunnions which coincides with the taper of the ladle shell and which transfers part of the weight of the ladle to the ring directly through the ladle shell, the remainder of said ring being spaced from the ladle shell to allow independent expansion and contraction of the same.

3. In combination with a ladle having an outwardly extending flange near the top thereofya support enclosing said ladle and having a pair of oppositely disposed trunnions thereon, comprising an upper ring spaced away from the ladle and upon which the flange of the ladle rests, and extensions on said said ring engaging the ladle shell above said trunnions only to transfer a portion of the weight of the ladle through the ladle shell.
